Online Assembly Guide : 6 inch Reflector Telescope INTRODUCTION Congratulations! You have bought a wonderful telescope. This is a precision optical instrument, and you have many wonderful evenings of observing the night sky ahead of you. This on-line guide is to help you assemble your telescope properly. Of course, the telescope comes with an assembly guide, and we were able to assemble our first telescope in exactly 1 hour and 15 minutes using that guide. We had never assembled a telescope before, so you can be assured that the paper assembly instructions will do the job. However, we know that many people are visually oriented and that pictures of the assembly process would be helpful. Since your telescope assembly guide and instruction manual does not have a lot of pictures, we have put together this online guide to help you assembly your telescope for your first night of observing. The paper guide in your telescope puts the telescope together in a slightly different order as we do in this online guide, so you may have trouble following both at the same time. Once your telescope is assembled and ready to go, the rest is up to you. Learning astronomy is all the fun anyhow! So let's get started . . .
ASSEMBLING THE TRIPOD Step 1: Find one of the three tripod legs as shown in Figure 1 below.

Step 2: Find the three tripod leg tightening screws shown in Figure 2 below.
Step 3: Insert the tightening screw into the side of the tripod leg as shown in Figure 3
Step 4: Find the base mount shown in Figure 4 below.

below.
Step 5: Find the base mount assembly parts. There are 3 sets of parts. Each of the 3 sets has 5 parts: 1 hexagonal ended bolt, 1 tightening nut, 2 large flat washers and 1 small flat washer. These parts are pictured in Figure 5 below.
Step 6: BE CAREFUL HERE. READ THIS STEP CAREFULLY! THEN READ STEPS 7 THROUGH 13 BEFORE CONTINUING ON TO THE NEXT STEP. Figure 6 shows what your are going to do in the next few steps. You are going to attach the base mount to the one end of the tripod. Please notice that there is a metal flap hanging off of the tripod leg in Figure 6 below. That is the mounting for the accessory tray. When you attach the base mount in the next few steps, be sure that the accessory tray mounting flap is on the inside of the tripod -- as shown in Figure 6. (Take a peak ahead at Figures 13 & Figure 20 to get a look at why those accessory tray flaps need to be on the inside).

Step 7: Insert the hexagonal bolt partway into the end of the tripod. Then place one of the large flat washers on the end of the bolt as shown in Figure 7.
Step 8: The first large flat washer should be set as shown in Figure 8 below.
Step 9: Next, attach the base mount to the tripod. Be sure to use the second flat washer on the other side of the tripod assembly as shown in figure 9 below.

Step 10: Place the small flat washer on the outside of the tripod assembly as shown in Figure 10.
Step 11: Make sure the hexagonal bolt is locked into place and flush (flat) with the assembly as shown in Figure 11.
Step 12: Screw the tightening nut on as shown in Figure 12.

tripod
Step 13: Repeat Steps 7 - 12 on the second tripod leg so that it is assembled as shown in Figure 13 below with the accessory tray flap on the inside of the tripod. Then attach the third tripod leg as well and you are done!
ATTACHING THE ACCESSORY TRAY You may want to find a small screwdriver you help get the accessory tray on good and tight.
Step 14: Locate the metal accessory tray and the component screws. There should be 3 round head metal machine screws, 6 small washers and 3 wing nuts as shown in Figure 14 below.

Step 15: Insert one of the screws and a washer into one of the small holes located on the rim of the accessory tray as shown in Figure 15 below. The accessory tray has a metal lip that will be facing upwards when the tray is attached to the tripod.
Step 16: Attach the accessory tray to the accessory tray mount flap on one of the 3 tripod legs as shown in Figure 16 below. Attaching the accessory tray to the outer most hole on the flap will provide the most stability for your telescope.
Step 17: Place a second washer over the screw on the bottom of the accessory tray flap as shown in Figure 17.

Step 18: Attach the wing nut to the bottom of the screw as shown in Figure 18.
Step 19: You may want to use a screwdriver, as shown in Figure 19 below, to hold the screw in place while you tighten the wing nut.
Step 20: Repeat Steps 15 - 19 to finish attaching the accessory tray to the tripod. When you are finished, the tripod should be assembled as shown in Figure 20 below.

ASSEMBLING THE EQUATORIAL MOUNT TRAY Believe it or not, you will be finished in just a few minutes. The rest of the assembly is very easy. Step 21: Find the equatorial mounting and the single large horizontal axis clamp screw, both shown in Figure 21 below.
Step 22: MAKE SURE THE TRIPOD LEGS ARE GOOD AND TIGHT!! Then, attach the equatorial mount to the tripod and tighten it in place from underneath using the horizontal axis clamp screw as shown in Figure 22 below.

Step 23: Insert the polar axis screw as shown below in Figure 23 below. Once that is attached, you can adjust the equatorial mount so that it is stable in an upright position.
Step 24: Attach one of the flexible cables (the declination flexible cable control) to the worm gear drive as shown in Figure 24 below.
Step 25: There is a groove in the worm gear attachment, use the thumb screw to tighten the flexible cable control to the worm gear drive as shown in Figure 25, below. Make it good and tight!

Step 26: Next, attach the other flexible cable (the right ascension flexible cable control) to the worm gear drive as shown in Figure 26 below. Be sure to tighten the thumb screw like you did in Step 25.
Step 27: Slide the counterweight onto the balance shaft as shown in Figure 27.
Step 28: Screw the balance shaft into the hole at the bottom of the declination shaft as shown in Figure 28. You can now use the set screw in the counterweight to hold the counterweight in place up and down the balance shaft. This will allow you to balance the telescope when it is completely assembled, making it possible to rotate the telescope smoothly by the slightest turn of the flexible cable controls.

FINAL ASSEMBLY OF THE TELESCOPE TRAY You are now ready to attach the main reflector tube of the telescope. Step 29: Remove the body belt from the main tube by unscrewing it from the main telescope tube as shown in Figure 29 below. Hang on to those round nuts, you will need them. (Note the plastic bag was previously removed before the photo in Figure 29 was taken)
Step 30 Attach the bottom half of the body belt to the equatorial mount by sliding it into position as shown in Figure 30 below. There is a notch in one side of the body belt (look closely at Figure 30) that is used to keep the body belt from sliding around. Use the tightening knob to tighten the body belt to the equatorial mount.

Step 31 When the body belt is attached to the equatorial mount, make sure that all of the various knobs and clamps are tight so that when you attach the telescope in the next step it does not rotate around and fall. You should set up the equatorial mount so that it is mostly horizontal, as shown in Figure 31 below.
Step 32 Carefully place the telescope on the body belt and tighten it in place with the upper body belt brackets and the round tightening nuts as shown in Figure 32 below.
Step 33 Next, remove the small eyepiece adaptor that is attached to the focusing tube, and replace it with the larger threaded eyepiece adapter into the rack and pinion focusing tube as shown in Figure 33 below. There is a thumbscrew on the eyepiece adapter that you can use to tighten it in place. The small eyepiece adaptor is used to permit smaller .965 inch eyepieces to be used with this telescope. However, the large eyepiece adapter (shown below) is what you need for the eyepieces that come included with your telescope.

Step 34 Attach the sighting scope to the main telescope tube using the round nuts as shown in Figure 34 below
Step 35 Smile! You did it. Now go enjoy your telescope. You probably will want to align the sighting scope during the daytime because it is easier. You should do this outside and point the telescope at something at least 50 yards away. Objects will be seen upside down through the eyepiece -- this is normal! When you are looking at distant stars, it won't matter if they are upside down. The owners manual has helpful instructions for alignment of the sighting scope.
